A series of metal-complexes of Co2+, Ni2+, Cu2+, Zn2+ and Pd2+ with new Schiff base named5-methyl-4-((3-fluoro-4-methoxybenzylidiene)-amino)-3-thiol-s-triazole have been synthesized andcharacterized. Schiff base is formed by the condensation of 3-fluoro-4-methoxy-benzaldehyde and4-amino-3-mercapto-5-methyl-1,2,4-triazoles (AMMT). After synthesis, Schiff base is characterizedby IR and NMR techniques. Metal complexes are characterized by different techniques as IR, NMR,ESR, electronic and fluorescence. Elemental analysis and magnetic measurements of metal complexeshave also been carried out. Using different techniques, tentative geometry for newly synthesizedcomplexes have been proposed i.e. square planar for copper and palladium complexes and octahedralfor rest of the metal complexes. The biological activities of all the metal complexes of this series arealso examined.
